GRAlN-SCOURER.

SPECIFICATION forming part of Letters Patent No. 507,903, dated October31, 1893. Application filed June 3, 1893. Serial No. 476-494. (Nomodel.)

art to which it appertains to make and use the same.

My invention relates to improvements in grain scourers.

The object of the invention is to provide a new and improved machine forconveniently, rapidly and thoroughly scouring and polishing grain, atthe same time separating the grain from screenings and other impurities.And it consists in certain features ofconstruction and combination ofparts, as will be hereinafter fully described and pointed out in theclaims.

In the accompanying drawings, Figure 1 is a transverse sectional view ofthe machine. Fig. 2 is a plan view thereof showing the means for raisingand lowering the drum. Fig. 3 is a longitudinal section view. Fig. 4 isa transverse view. Fig. 5 is a detail showing clamp.

A represents a shaft having the drum pulley A, mounted in the elongatedslots 0 formed in a suitably constructed receptacle B. This shaft isprovided with a series of al ternating fingers O, forming stirrers oragitators. The shaft A is provided with the collars a and b to preventhorizontal displacement, and with the bearings c, to receive the axialbearings d on the drum D. The drum is cylindrical in shape, and isformed in two sections,E and F, and are suitably hinged together at oneside. The section E is preferably of solid material e, such as tin orother water-proof material, while the section F is made with wireforming a sieve b, or it may be made of reticulated or any othermaterial, as may be preferred; or, if desired, both sections of the drummay be made of perforated material. The sides of the drum are connectedtogether by means of the batten d. The bearings c and d are loose onesso as to allow a free rotation of the shaft A, without communicating anymovement to the drum D. The sections of the drum are locked together bymeans of the hooks G, on the sides thereof, and by means of the screwclamps H,wh1ch for absolute security, are placed over the hinged andopen sections thereof. These clamps form an important feature in view ofthe immense weight and bulk contained in the drum.

To one side of the receptacle B are secured two heavy sheet metalstraps, G, the opposite ends of which are loosely secured to the leatherstraps H, which are fastened to the winding shaft I, said shaft beingjournaled 1n the bearings 2', formed in the frame B; one end of theshaft is provided with a wheel K, having a series of perforations toreceive a removable crank L.

The bottom of the frame Bis provided with a sluicel and gate m.

The operation of the machine is as follows:-The shaft and drum areraised nearly to the level of the receptacle by means of the shaft I,and are held in such position by means of the handle bar L, which ispassed through one of the holes 70, one end thereof resting on the frameB. The section F is then raised, and the grain and water are put in thesame, falling on the section E. When filled, the sections are lockedtogether, as shown. The drum is then gradually lowered until the shaft Ais at home. Power is then applied to shaft A through the pulley A bymeans of any suitable drive belt. When the grain has been sufficientlyscreened, the drum is lifted to the top by means of the winding shaft;it is then revolved until the sieve section F is bottomward. This willnaturally cause the water, together with the screenings and otherimpurities, td flow into the bottom of the receptacle, from which theyare released by means of the sluice.

When the entiredrum is made of reticulated material, the water will becontained in the bottom of the receptacle, and the operation is thesame.

Having described my invention, what I claim is 1. Ina grain scourer, thecombination with a liquid receptacle, of a vertically adjustable rotaryshaft supported in hearings in said receptacle, a drum loosely mountedupon said shaft, and lifting straps secured at one end to the receptacleand passing beneath the drum and at their other ends to a winding shaft,for the purpose'specified.

2. In a grain scourer, the combination with the frame of a verticallyadjustable shaft supported in bearings in said frame, a drum looselymounted. upon said shaft, straps se cured one side to the frame andpassing beneath the drum, and at their other ends so cured to a windingshaft, said shaft having a Wheel affixed thereto and provided with aseries of perforations, in any one of which is (5 specification in thepresence of two subscrib- 2o ing witnesses.
